is the type; it answers the descriptions given by Fabricius and Olivier, and it has been compared with a modern example of this species in the British Museum Collection.

Olivier's figure of this type is a good representation, except that the subpectinate character of the antennae is not clearly shown.

Description of Type, Pyrochroa flabellate Fab. This example is a male. Form elongate and rather narrow; the head subtriangular and exserted, conspicuously projecting, horizontal and strongly constricted behind the emarginate eyes, and with subpectinate antennae; the thorax subquadrate but rounded at the angles, and broader than the head; the long elytra much wider than the thorax, parallel-sided, with very rounded apices divergent at the suture. The front and middle tarsi five-segmented, the hind tarsi four-segmented, and the penultimate tarsal segments bilobed. The head, the basal segments of the antennae, the thorax, legs and abdomen glossy light reddish yellow; the eyes, the antennae (except the proximal segments), and the elytra uniformly glossy brownish black; the surface of the head unevenly impressed and lightly coated with fine silky hairs.

The head is subtriangular and conspicuously exserted, projecting horizontally; it is strongly constricted at the neck and somewhat dilated behind each eye. The vertex is convex and narrowed between the eyes; the fronto-clypeus is strongly impressed on the frons, there is a deep pit on the inner side of each antennal insertion and the clypeal portion is narrowed and convex; the transverse clypeo-labral suture is almost straight, the labrum is transverse and rounded in front. The maxillary palps are light red (yellowish red), long and exserted, with the distal segment elongate and cleaver-shaped. The mandibles are brownish red.
